made a trip from Long Island to Poconos, mostly highway and no traffic. after my full tank of all highway miles, I got around 14-15mpg. I dont remember the exact number. and yes i manually worked it out to get that number. i feel like i should be alot higher for all highway miles. I did though have 3 other people in the jeep and all our snowboarding gear. as well as the rubi and 4.10s. would all that sound reasonable? or does it still seam low.
